To all -wwm im may coreani.:

Be it know; that l,- Gnoncs F. Minnen, a citizen of the United States, residing et Easton, in the. county of ortnnrnpton and State of Pennsylvania, have invented certain newI :nid useful linproyeinentsin Packing, of which the following 1s' a specication.

This invention relates to improvements in packing. and particularly' to packing for valves, joints'and the like where friction is present.

The object in view is the provision of means arranged for lubi icating and packing a joint er va ve or the like at the same time.

Another object in vievsr is `the arrangement of s soit metal and a liquid lubricant, to-

' gelber with binding mea-ns for presenting s combination packing and lubricant that hes n comparatively long, life.

A. still further object of the invention is the arrangement of shredded Babbitt. metal, asbestos rope.' oil and graphite intermixcd and twisted together for forming e. comb'med packing and lubricant..

W'ith these and other objects in view tire invention comprises certain novel constructions, combinations and, arrangement of parts as'will be hereinafter more fully de scribed and claimed.

In the accompanying drawings: Figure l is 9g lan view of the combined packing and lubricant arranged with certain parts re moved for disclosing the structure thereof. Fig. 2 is a plan vien of the packing with the edges turned in. Fig. 3 is a perspective View of the packing with the edges turned in and one corner slightly rolled. Fig. 4 is a side elevation of the complete packing rolled and twisted. Fif. is a section tnrough Fir. s, approximately on line 5-5 thereof.

fn constructing n packing embodying the invention, Babbitt metal is taken and shredded to any desired extent, but preferably in comparatively small strings of:

ieces. The Babbitt metal after having` en shredded is spread out in a thin layer and then a number of comparatively small strands of Wick asbestos are arranged or scattered over the layer of shredded Bibbittv metal. The shredded Babbitt metal is ar- 'ranged in a thin layer of such length 'and breadth as will be necessary to make the contemplated size packine. The asbestos wick or ro Iis arranged lengthwise of the layer of abbitt metal so as to extend turned in and thon the lengthwise or' the packing when complete.

Upon the top ci the asbestos is laid lenilr wise :mother lsyer of shielded Babbitt metal which is comparatively thin, 'the sante as the iirs layer. Another lsyer of 'wick asbestos is placed upon the. second layer of .Babbitt instel and arranged in rows a'siiort distance apzirt, A third lai-'er of shredded Babbitt rnetelsiconiparatively thin, is placed upon the second layer of asbestos Wick.

desired layers of Babbitt metal may be provided according to the size o packing desired. rter the lest layer of Babbitt metal has 4been laced in positionoil and graphite isspriniii A per surface of the finished pile The oil and graphite may be placed in position seperntely or may bernixed first and then sprinkled upon the pile of Babbitt metal and asbestos. 'Any desired quantity of oil and gra bite may be placed upon thev pile of Babbitt metal and asbestos according to the. ann-ent o' oily matter desired in the selling, s conipetetively small amount 'be- :ng preferable. .sitter the oil and aphite have been placed in position all of t te outer: edges, both on each side end the ends, are Babbittmetal is rolled up commencing at one corner and ending. at the diagonl opposite corner. This rolling will cause the asbestos Wick or rope and also the shredded Babbitt metal to be wound something like an ordinary rope structure. After the packing has been thus rolled up the Semois twisted in the direction in which it has been rolled which twisting fiction will squeeze t-licoil and graphite through the entire body until the same begins to onze ont. when thevtwisting action will cease.

In order thnt'the invention may be more clearly understood, an embodiment of the same is shown in the accompanying drawings in which l indicates a layer ot' shredded Babbitt metal upon which is placed rows of wick or rope asbestos 'l which are spaced apart any desired distance. Upon the top layer l of Babbitt metal is positioned the oil and ginphite 3. ln forming thc packing :tnv desired numbers of layers of shredded Bcibbitt metal l may be provided and bctween each layer is vpror'nled the asbestos rope or wick 2. After the desired thickness of Babbitt metal and asbestos has been secured the oil :ind graphite 3 is placed in poed or spread over the up 10 enrner, whereby tbe asbestos rope 20 itl the Babbitt.

sition upon tbc top layer, either or after having been previously mixed. The packing is then folded :1s shown in Fig. 'Z in which the edges 4 and 5 :ire folded inward,

5 `and :Liso tbe end-t 6 and 7. After the packing bis been arranged as ebown in Fig. 2 tbe saine is oiied starting at one corner as :it 8, asrsbown in Fig. 3. The packing is rolled from one cox'ner to tbe diagonal oppoeite y 2 will be twisten something en tlie order of an ordinary rope. Afm' the panting has been rulli-d tbe .Qmnc twieted until tbe oil and frapbite begin to ooze mit the outer sufran-e.

'l5 This distributes tbe oil and graphite encient-ly smooth :and lubricant. mnning in tbe packi t-innally act though to 2-5 having been us'ed for n Considerable time.
